By Leibniz Institute for Solid State and Materials Research Dresden - IFW Dresden
At IFW Dresden the materials for electrochromic devices can be characterized. Hence, the influencing factors of the charged species, which determine the color of the devices, can be defined. With our long-standing expertise and comprehensive analysis of a variety of spectroscopic methods, which are combined with electrochemistry, changes in structure, properties and stability can be followed in situ. Only materials of purely organic compounds, organometallic complexes or electroactive polymers can be analyzed by the described methods. Identification of species, which are responsible for color change Concentration profile of the electrochemically generated species in dependence on stepwise varying potential Accurate in-situ spectroelectrochemical techniques using Nuclear magnetic resonance (NMR), Electron spin resonance (ESR/EPR), Raman, Fourier Transform Infrared (FTIR), Ultraviolet-visible-near-infrared absorption (UV-vis-NIR) and Luminescence spectroscopy Triple method of ESR/ UV-vis-NIR/ cyclic voltammetry
